A major change happened in 1939 with the publishing of the book Salvation. Rutherford decided that Adam could not be fogiven after all.
This was actually published before in 1938; in that same year Rutherford introduced his view that all outside of what he considered to "Jehovah's organization" would be eternally destroyed at his idea of Armageddon.
However, long before this, in 1923, he introduced a new view of the second death and the sheep and goats, in which he claimed that many who have never been englightened have gone into the second death, and thus will not be raised in the day of judgment.
Thus, this was when he actually rejected the ransom for all that Russell taught. In 1938, however, when he stated that Adam was not covered by the ransom, he actually rejected the very basis of the ransom.
The condemnation of Adam was not a different condemnation than that of human race condemned in Adam. If Adam is not to be restored to life, this would mean that Adam did not die the death in Adam, and must have therefore died the second death. This would, in effect, mean that the death in Adam is actually the second death. This, in turn, would mean that the whole human race was condemned in Adam to the second death. And thus the self-contradiction of this error becomes apparent.
If Adam's sin was such that no ransom could be provided for it, this would mean that the condemnation of Adam could not be ransomed, and therefore those who are condemned in the condemnation of Adam cannot be ransomed.
Jesus paid the debt for the condemnation upon Adam. All were condemned in one man so that only one sinless man would be needed to redeem all. The same condemnation that was upon Adam came upon the whole human race. ( Romans 5:12-19 ; 1 Corinthians 15:21 , 22 ) There was not one condemnation upon Adam and a different condemnation for the rest of mankind, as the Watchtower, and some others, teach. Jesus paid the penalty that was upon Adam. If he didn’t, then none of us have been redeemed, since it is the penalty upon Adam that is the whole basis of the ransom. If Jesus paid the condemnation upon Adam, and if the condemnation upon the human race is a different condemnation, then only Adam is redeemed, and the human race in Adam has not been redeemed. Only if it is the same condemnation could there be any application of the ransom to the whole world of mankind. And since it is the same condemnation, as can be seen in Romans 5:12-19 and 1 Corinthians 15:21 , 22 , then Jesus did indeed pay the price for the condemnation of Adam, and thus Adam is included in that ransom, and would be due the benefits provided by that ransom.
